Four Days of Mindblowing Music at Bonnaroo wraps with Robyn

The last day at Bonnaroo is a bit of an endurance test. By this point, most of the 80,000 campers have gotten so sun-fried they could take a Frisbee to the face and not blink. (If you ever wanted to see what a hacky-sack-playing zombie looks like, Sunday was your chance.) So it fell on the artists to whip them into shape. One who did was Swedish pop queen Robyn, who celebrated her birthday with a disco party that felt more like midnight on a Friday than a hot Sunday afternoon.
